PATH ANALYSIS IN DRY BEAN GERMPLASM

Abstract

The analysis of inter-relationship among the different characters in 91 germplasm lines of rajmash (Phaseolus vulgaris L.) during three growing seasons, showed that grain yield was positively correlated with number of nodules, number of pods and pod length, but was highly significant with plant height. The path coefficient analysis revealed that pod numberwas most important yield character. The metroglyphic analysis showed that race-1 and race-S genotypes were higher yielder and revealed a direct relationship between plant height and crop duration, whereas inverse relationship between plant height and pod/grain degeneration was evident. These characters, therefore could be used as useful criteria for developing high yielding rajmash varieties suitable for different growing seasons.
